Subject: [PATCH 3/5] dt-bindings: timer: microchip,sam9x60-pit64b: convert to yaml

Convert Microchip PIT64B to YAML. Along with it clock-names binding has
been added as the driver needs it to get PIT64B clocks.

+  The 64-bit periodic interval timer provides the operating system scheduler
+  interrupt. It is designed to offer maximum accuracy and efficient management,
+  even for systems with long response times.
